    • The solutions of Eqs. 4 and 5 for the oscillation amplitude and phase shift φ relative to the forcing for P′ are (Formula Presented) For conditions on the approximations in Eq. 5, see (27). The coupling coefficients α and μ are positive and αμ < 1 so that the positive feedbacks do not become unstable. In Fig. 3, αμ = 0.5.
